Poland, officially the Republic of Poland, is a country in Central Europe. With a population of 38 million people, Poland is the 6th most populous country in the EU. EU/EEA students do not need a visa to study in Poland. The cost of living in Poland is among the lowest in the European Union.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
